Although I already read about this and from time to time checked it in both my dictionary and my grammar books and even I understand all the differences which Josef has perfectly explained I have problems with the words (aspects of the mentioned verbs) if I have found them in texts (novelas) I read.

I am not a teacher but learner but wanna say that I think that one who doesn't have any problem with its meaning and gets the meaning in a 1/100 part of a second and also pronounce the words perfectly speaks advanced English.
